PILOTIroshizuku Bottled Fountain Pen Ink, Shin-Kai, Deep Sea (Blue Black) 50ml Bottle (69225)

The ink arrived in perfect condition, in a nice silver box and secured in a plastic bag. I haven't tried it yet, but it looks to be a beautiful shade of blue. And you get a good amount of ink in a really nice, heavyweight bottle.

Great colour. Super quality, it stands out from competitors. Dry quickly, no smudges.

It's fairly rare for me to "try" reviewing products unless they're worth buying.Hopefully, for those unsure:I haven't bought every ink, but I have enough to compare.0. The raw files are too large, so edited ones will have to do.1. They outperform Waterman and everything else for those who "smudge."2. I returned the grey one because it was "too light." My bad. It's totally great for annotations in books and whatnot.3. Take-sumi is my favorite, including comparisons with Noodler's, Carbon Platinum, and Waterman. (Sailor might be better.)4.

Lots of reviews don't capture color very well. Each image was taken at 50 ISO, 1/4 speed.Image 1: Ambient + 2x 2700K 1600-lumen CFL bulbsImage 2: Ambient + 1x 2700K 1600-lumen CFL indirectImage 3: Ambient only (2x GE 2000K 125-lumen indirect)Could not capture daylight well.7. Each bottle was shipped in a box, packaged well. No spills or issues.8. A guaranteed smudge-free black and blue are Sailor's, but these outperform in many other ways.9. Don't be disappointed if the color is not what you're expecting.[*] Comparison with Pilot PrepaOverall, it seems like the lighter colors are more suited for annotations or highlights. These will probably end up getting used more in day-to-day activities than the darker ones. I will likely repurchase the grey eventually. Each light color is dark enough to be legible in a book or while grading but subtle enough not to stand out.5/5

It seems to hold a lot of bubbles, but the flow and thickness are both very pleasant to write with. The color is a nice soft red toward the blue end of the spectrum. The drying time isn't half bad either. I tried writing on printer paper, card stock, and craft paper, and they've all held the ink beautifully without bleeding or beading.

Great ink by Pilot.. love the color and properties of the ink

There are faster drying inks out there but over all it works great. When writing the second line down, I tend to smear the first line.

If you don't buy ink from this company, then we can't be friends.I'm sorry.Seriously.This ink is absolutely beautiful and absolutely worth every dime i swearThank you

Is a bit on the pinkish side of vermillion, but is a very good ink and a pretty color. Flows well, works great with Jinhao pens
